    This was the first live tubeworm seen at a hydrothermal vent site in Atlantic waters.If ocean exists and a volcanic activity exists within, there may be hydrothermal vents on the ocean floor.The irony is that once scientists knew what to look for, they went to other well-known ecosystems that were rich in hydrogen sulfides, such as salt marshes, and found the same mutualistic association of chemosynthetic bacteria and animals that had stunned them in the deep vents.This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek φῶς, phōs, "light", and σύνθεσις, synthesis, "putting together".Such values are expected for clams harboring thioautotrophic symbionts, suggesting that the fossil was dependent on chemosynthesis during its lifetime.The organic compounds are formed using geothermal energy.These organisms are able to produce carbon molecules through the process of chemosynthesis, while other, more complex microorganisms dwelling in dark regions of the ocean are responsible for generating biomass from single carbon molecules.This kind of reaction involves the loss of electrons from one substance and the adding of electrons to another.Chemosynthetic bacteria use inorganic molecules, such as ammonia, molecular hydrogen, sulfur, hydrogen sulfide and ferrous iron, to produce the organic compounds needed for their subsistence.The discovery of hydrothermal vents, cold seeps and gas hydrates in subsurface sediments and rocks showed that significant ecosystems on Earth are fuelled by reduced chemical substances (H).Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent.

    Instead, the microbes get their energy from different chemicals in hydrothermal fluid.The model is constructed using information from "Our Changing Planet" by Fred T. The model is then altered by the introduction of human fluxes and evaluated using information from the National Geographic Society magazine article "The Case of the Missing Carbon".Photosynthesis takes place on land and in shallow water where sunlight can reach seaweeds.For example, some get their energy by breaking down hydrogen sulfide.Close up of a tubeworm “bush,” which mines for sulfide in the carbonate substrate with their roots.Students should have been introduced to the concepts of atoms and elements, the reactions for photosynthesis and respiration, food chains, the age of Earth, and have some knowledge of global change. All the boxes must be connected by arrows that are labeled by the activity, e.g., "buying lunch".Chemosynthesis is the process by which food (glucose) is made by bacteria using chemicals as the energy source, rather than sunlight.The formation of organic compounds using the energy released from chemical reactions instead of the energy of sunlight.Although these symbionts have yet to be cultured, physiological, biochemical and molecular approaches have provided insights into symbiont genetics and metabolism, as well as into symbiont–host interactions, adaptations and ecology.During chemosynthesis, bacteria living on the sea floor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide (dissolved in sea water).

    Many microorganisms in dark regions of the oceans also use chemosynthesis to produce biomass from single carbon molecules. In the rare sites at which hydrogen molecules (H) can be large enough to drive the production of biomass.It has been hypothesized that chemosynthesis may support life below the surface of Mars, Jupiter's moon Europa, and other planets.Some groups of these bacteria are well suited to conditions that would have existed on the earth billions of years ago, leading some to postulate that these are living representatives of the earliest life on earth.The temperature of water around these vents is about 350° defined as the biological production of organic compounds from one-carbon (C-1) compounds and nutrients, using the energy generated by the oxidation of inorganic or C-1 organic molecules.Basically, it’s all about the process that specific organisms use to get the energy necessary to produce food, and it’s quite similar to photosynthesis (but without using the sunlight).In most cases, oxygen is also released as a waste product.
